I have today signed into law S. 1175, the "Vicksburg National
Military Park Boundary Modification Act of 2002." In 1863, union
forces under the command of Major General Ulysses S. Grant and
confederate forces under the command of Lieutenant General John C.
Pemberton fought for control of Vicksburg, Mississippi, a strategic
location on the lower Mississippi River. The Act authorizes the
Secretary of the Interior to add the confederate commander's
headquarters to the Park, which has included the union commander's
headquarters for many decades. The Act will enable the Department of
the Interior to preserve property for the education of Americans today,
and in generations to come.

The second sentence of section 3(b) of the Act reads: "Upon the
acquisition of the property referenced in this subsection, the
Secretary add it to Vicksburg National Military Park and shall modify
the boundaries of the park to reflect its inclusion." It is plain in
reading the sentence that a word is missing between the words
"Secretary" and "add."

In accordance with section 106 of title 1 of the United States
Code, enrolled bill S. 1175 was presented to me bearing the signatures
of the Speaker of the House of Representatives and the President pro
tempore of the Senate, which attests that both Houses passed the bill.
In accordance with the principles enunciated by the U.S. Supreme Court
in Marshall Field & Co. v. Clark in 1892, I take the bill presented as
being duly enrolled and shall not turn to the journals of either House,
the reports of congressional committees, or other documents printed by
the authority of Congress in an effort to determine whether an error in
the enrollment of S. 1175 has occurred.

Recognizing that the second half of the sentence in issue provides
that the Secretary "shall" modify park boundaries to reflect inclusion
of the property in the Park, the most reasonable construction of the
first half of the sentence is that, after the Secretary of the Interior
acquires the property, addition of the property to the Park by the
Secretary is mandatory. Accordingly, the executive branch shall
implement the second sentence of section 3(b) of the Act in the same
way it would implement the Act if the word "shall" appeared in that
sentence between the words "Secretary" and "add." This construction is
faithful to the legislative intent as evidenced by the content of the
statute itself.
